See how valuable an electronic collar, or e-collar, can be to your dog as James Hamm, Lone Star dog trainer and president of the International Association of Canine Professionals, discusses the advantages to training with one, such as the Delta XC, Delta Sport XC or Delta Upland XC from Garmin. An e-collar not only lets you communicate with your dog at a distance but it’s also a great training tool for dogs that do not like leashes or get extremely excited in certain situations. The collars are easy on the dog and easy on the people.
